Pros
This is a heavy Microsoft shop, and they stay on the cusp of Microsoft's software ecosystem. If you can survive the overbearing management, it can provide a great opportunity to grow professionally if you enjoy working with Microsoft products. Salary can be competitive for the Dallas area market.
Cons
Management. This may seem like a cliche that you've read in review after review, but in my nearly 20 years in professional IT, this is the worst management I have ever seen. The management's treatment of employees is repulsive. If you've never worked for a megalomaniac you'll have the opportunity to do so here. You'll feel like you are slipping into that job you worked in High School. Turnaround is obscene. If a system administrator has been there for over a year, he is considered "senior". I personally witnessed 10 people either be fired or quit within 6 months. Constructive criticism or guidance is not provided, you will simply be walked out. It's imperative that you have a backup plan if you are a major financial provider in your household! Don't let the recruiter sell you on the position. DFW has a very competitive IT market, and I strongly advise you look elsewhere.
